Application filed March 30, 1922. Serial No. 547,973.

2 0 (IE whom it may concern Be it known that l, WILLIAM S. Bscnronn, acitizen of the United States, residing at Newark, in the county of Essexand State of New Jersey, have invented new and useful Improvements inArticles of lilanufacturc, or which the following is a full, clear, andexact specification.

My invention relates to articles of celluloid-like composition andrefers particularly to multi-colorecl articles or" that description.

Celluloid and similar material are well adapted for the production ofmany articles, particularly so-called toilet articles. on account of itsease of manipulation, durability and capability of producing artisticcilects, hence, they have been largely adopted for articles of thischaracter. a

it is essential that articles of this general class be strong, durableand free from tend ency to warp and it is further advantageous that theybe of artistic appearance, espc cially as regards their color or colors.

The device of my invention possesses all of these desirablecharacteristics and presents a means for the production of such articlesin an economic manner.

I have founc that articles of superior (luability and freedom fromwarping can be produced by the proper cementing together of plurality oflayers of celluloid. or similar material, in which the inner layer, orlayers, extend outwardly beyond the exterior layers and l have furtherfound that when layers of difi erent colors are thus employed it ispossible to produce artistic and attractive color effects not otherwiseobtainable.

The value of my invention, particularly as it refers to color etiects,will be evident upon a consideration o1 the elements of my invention andthe class of articles to which it refers.

ln the commercial application of my invention, ll prefer to employ threelayers of celluloid, or similar material, the two outer layers being ofpractically the same color. while the inner layer is of a diticrentcolor,

the inner layerextending beyond the two ex-.

terior layers.

By this means, l am able to obtain a device free from danger of warpingbecause of the overlying layers of material and which Will have asimilar multi-colored etl'ect upon both, sides of the article.

ill invention is particularly adopted for the production of combs, inwhich case stab1l1ty and flexibility are produced at the requisiteportions thereof, with the turth r roduction of desirable and artisticcolor c1":- Iects not otherwise producible.

ln combs of this character, it is desirable that the back, or base, ofthe comb be as" stiff and non-resilient as possible, whereas the teethof the comb should have certain amount of flexibility, or resilicncv, inorder that they may not have a harsh effect upon the hair through whichthey are drawn.

The combs of my invention have both of ti ese valuable attributes.

in producing the combs of my invention, I employ a blank composed ofthree levers ot' celluloid, or similar material, cemented togcther, theinner layer being of a different color from the two outer layers.

For purposes of illustration, it may be assumed that the two outerlayers are of tortoise-shell color and the inner layer of a clear ambercolor.

The back of the comb comprises the tnree layers of the. material,preferably having the inner layer extend beyond the outer layers along,the run of the back, thus giving that portion of the comb the fullrigidity and freedom from warping of the three lay-er material.

The teeth of the comb are formed by a gradually increasing wearing awayof he two outer layers, thus brin inp the teeth into an approximatelypointe allowing the actual ends of the teeth to be rounded to preventthe scratching or cutting of the head when applied.

The thickness of the layers and the pitch of the inclineot the teeth are.so arranged that, while the upper portion of the teeth carry the fullthickness of the outer layers, these layers gradually decrease and areentirely removed before the end of the teeth is reached.

The physcial cilcct of this formation is that, while the upper portionotthe teeth have the full rigidity of the three layers. this graduallydecreases until thelower portion oi the teeth consist of only the innerlayer and thus have considerable flexibility. The optical ed'ect of thisformation, in

the example given, is that the shell color effect 01'' the back andupper portion of the teeth gradually disappears and is blended into apure amber color at their lower portions, the artistic effect beingenhanced by condition, while the fact that there is no abrupt line ofdemarkation between the two colors.

A consideration of the above and of the accompanying drawings anddescription will evidence the novelty of my invention and its usefulnessand attractiveness.

ln'the accompanying drawings, illustrating one form of a device of myinvention, similar parts are designated by similar numerals.

Figure 1 is a side plan view of a comb illustrating my invention.

Figure 2 is'a cross-section through the line 22 of Figure 1.

The illustrated device showing a comb formed of three cemented layers ofcelluloid comprises the exterior layers 10. and 11 of a similar darkshell color and an inner layer 12 of a clear amber color, the threelayers being cemented together.

In the upper portion of the back, or base, of the comb, the inner layer12 extends beyond the two exterior layers 10 and 11.

Below the line AA, the celluloid material is cut, or teeth 13, 13, theouter faces of which are gradually reduced until the lower portions ofthe two exterior layers 10 and 11 are entirely removed, thus allowingthe inner layer 12 to be exposed beyond the two exterior layers 10 and11. In the formation of the teeth the back is cut away at 14c and theteeth slightly cut away at 15.

It will thus be seen that by this means of construction, the back andupper portions of the teeth have the full rigidity of the three layersof material while the teeth have a gradually increased resiliency, orflexibility until they have finally the full flexibility or the innerlayer.

-l't will be further seen that the back will have the, shell-coloreffect, topped by the extended amber color. and this shell color willgradually blend into the amber color along the teeth faces, there beingno decided line of demarkation between the two. this appearance beingfurther enhanced by the semitransparency of the celluloid.

formed, into a plurality of assen By celluloid in my specification andclaims, I mean celluloid or any other substance, or material, suitablefor the carrying out of my invention.

I do not limit myself to the particular size, shape, number, color,composition or arrangement of parts, nor to the particular article ofmanufacture shown in the accompanying drawings, which are illustratedthe faces of which the exterior layers are gradually decreased inthickness,

exposure of the interior layer.

3. In an article of manufacture, in com bination, a comb comprising aback comcausing an posed of three thicknesses of celluloid of variedcolors and a plurality of teeth upon at least a portion of the faces ofwhich the exterior layers are gradually decreased in thickness, causingan exposure of the in terior layer.

4. In an article of manufacture, in combination, acomb comprising a backcomposed of three thicknesses of celluloid ot' "aried colors having anexposed portion of the inner layer extending beyond the exterior layersand a plurality of teeth uponat least a portion of the faces of whichthe exterior layers are gradually decreased in thickness,

causing an exposure of the interior layen.
